Time-Resolved Physically Unclonable Functions Enabled by Solvent-Free Scalable Boron-Based Ultralong Phosphorescent Systems for Machine-Learning-Resilient Optical Encryption.

Anti-counterfeiting technologies are increasingly challenged by advances in imaging and machine learning, exposing the fundamental limitations of conventional static optical security systems. Here, a time-resolved physically unclonable function (TR-PUF) system is established, transforming optical authentication from st...
